  2.   

    代码太长，没看。
    只说一下思路:
    1.用curl把图片保存下来，同时要保存cookie
    2.验证码识别（机器识别也好，手工识别也好）
    3.用第一步的cookie，提交登录数据
      

  3.   

    $ch1 = curl_init();  
    curl_setopt($ch1, CURLOPT_URL, "http://www.ems.com.cn/servlet/ImageCapServlet");
    curl_setopt($ch1,CURLOPT_REFERER,$url);
    curl_setopt($ch1, CURLOPT_HEADER, false);
    curl_setopt($ch1, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch1, CURLOPT_COOKIEFILE, $cookie_jar);
    $img = curl_exec($ch1);
    curl_close($ch1);
    file_put_contents('img.tmp', $img);
